The invention relates to a feed line for supplying power to electrical components of a motor vehicle and transmitting information between at least some of said electrical components. The inventive feed lines are arranged particularly in a star topology comprising at least one star point. In order to be able to transmit large supply currents, the feed line structure is embodied such that at least one part of the feed lines (10) is provided with a coaxial arrangement of several outer strands (4) that are located around a central strand (2).
